How do i display the old responses of returning respondents to my new survey with follow up questions?

I need to design my new survey based on the fact that they may have filled out a previous survey and i need to know how to display the previous survey responses here asking them to edit if anything has changed since the last time they filled it out.

I read this article: https://help.surveygizmo.com/help/prepopulate-a-survey-login-password-action

It helped alot to construct the survey but i need help in the final customization to show the previous survey responses
